Bearing NA4906 used in what local summary: NA bearing inner ring device inner ring outer ring full set of bearings adhere to the available speed local mechanical motor demand shaft in the normal transition of the work brake state of the shaft conditions require a small amount of axial displacement using this bearing can be easily Simplified mechanical layout Most types of rolling bearings have this function. Brake cone rotor motors use this kind of bearing liquid dynamic pressure bearing common axle housing shaft
The NA0000 (54000) type bearing inner ring has no ribs. Therefore, the inner ring and the outer ring (with a full set of needle roller and the holding frame) can be separately installed. This type of bearing has an apron that can be used at a higher speed.
Some machines and motors; the demand shaft is normally changed and braked during operation; the shaft requires a small amount of axial displacement in two working conditions; the use of this bearing can easily simplify the layout of the machine; and most types of Rolling bearings do not have this function.
Such as a cone rotor motor with brake; use this bearing.
